Body Area Sensor Network

• Vibe is a low-power, wireless body motion sensing platform.

• Vibe can network with up to 5 additional devices to create a wireless Body Area Sensor Network.

• Vibe has a 6-axis IMU for advanced motion tracking.• Internal extended storage allows Vibe to log motion data

for analysis by physicians, researchers.• Rechargeable battery with >1 week battery life for a

typical application.*

What is Vibe?

• Mother of a child with chronic epilepsy was required to sleep in close proximity of her son to medicate before onset of a seizure.

• Envisioned Vibe as a body tremor sensor to detect onset of seizures and alert caretaker.

• Development and deployment to researchers of a wireless body motion sensor with a rich and easy to use API.

• No current product on the market that has the feature set of Vibe.
